Refactor ReagentGrinder (#11751)

* Refactor ReagentGrinder

- It can now process partial stacks. (Before it would do nothing if the entire stack's solution didn't fit in the output container)
- Get rid of `SharedReagentGrinderComponent`, move shared stuff to `SharedReagentGrinder.cs`.
- Subscribe to events instead of massive switch/case.
- Get rid of update queue thing.
- Change `DoWork` so it's less duplicate code for grinding/juicing.
- Get rid of `ExtractableScalingEvent` and just scale directly based on item stack count.
- Add message for when you try to put something into the reagent grinder that doesn't fit.
- Fix obsolescence warnings.

* Use a timer on component instead of SpawnTimer

* s/StorageCap/StorageMaxEntities
